During normal operation the instrument display shows a steady GREEN backlight.
During Low and High Gas Alarm it displays a ashing RED backlight

The screen is visible through the window of the transmitter’s cover. The display shows the
gas concentration (both graphically and numerically), range, units, alarm/

Note: The detector display may become sluggish in sub-zero temperatures and possibly
unclear at temperatures below -40 °C, but the detector continues its gas monitoring
function. The display is not damaged and recovers when the temperature increases.
